For part A. 0.85

For part b. 11.9

Explain

Cost of each track in album A= total cost downloading album a/ total number of track

The problem give us a has 11 trackers and the total cost of download is 9.35 pounds

9.35/11

= 0.85

Now we are given each track cost in album b cost the same as track on A

Cost of each track in album B is 0.85

Now we are given if Jane download album B , B will be 14 tracks

Total cost of downloading is album B= number of tracks in album Bx cost of each track in album B

14x0.85 pound

= 11.9

3x+4y+6z=15 Solve for x.

aalyn [17]

Answer:

Step-by-step explanation:

<h3>Question:-</h3>

To solve for x

<h3>Equation:-</h3>

3x + 4y + 6z = 15

<h3>Solution:-</h3>

=> 3x + 4y + 6z = 15

[On subtracting both sides with 4y]

=> 3x + 4y + 6z - 4y = 15 - 4y

[On Simplification]

=> 3x + 6z = 15 - 4y

[On subtracting both sides with 6z]

=> 3x + 6z - 6z = 15 - 4y - 6z

[On Simplification]

=> 3x = 15 - 4y - 6z

[On dividing both sides with 3]

$= > \frac{3x}{3} = \frac{15 - 4y - 6z}{3}$

[On Simplification]

$= > x = 5 - \frac{4}{3} y - 2z \: (ans)$

What is275,608 rounded to the newest thounsand

kumpel [21]

Stays the Same: 1,2,3,4
Goes Up: 5,6,7,8, etc...

1. The number 5 is located in the thousands place

2. Since the number 6 is located in the hundreds place, it's telling 5 to go up a number (turning 5 into a 6)

275,608 ⇒ 276,000

So the answer is 276,000

Find the 52nd term of the following arithmetic sequence. 3, 9, 15, 21,

Alex Ar [27]

Answer:

309

Step-by-step explanation:

a = 3, d = 6, n 52

Nth term of an Arithmetic sequence is given as:

$t_n=a +(n-1)d \\ \therefore \: t_{52}=3 +(52-1) \times 6 \\ \therefore \: t_{52}=3 +51\times 6 \\ \therefore \: t_{52}=3 +306 \\ \huge \red{ \boxed{\therefore \: t_{52}=309 }}\\$

Can I please get some help

Aleksandr [31]

Answer:

a. $1.76$

b. $2.5$

Step-by-step explanation:

You have the following formula given in the exercise:

$t=\frac{\sqrt{100-h}}{4}$

a. If the object is 50 feet above the ground, you can identify that the value of the variable "h" would be the following:

$h=50$

Then, knowing that value, you can substitute it into the given formula and then evaluate in order to calculate the time in seconds for the object to be 50 feet above the ground.

This is:

$t=\frac{\sqrt{100-50}}{4}\\\\t=1.76$

b. When the object reaches the ground, the value of "h" is:

$h=0$

Therefore, substituting this value into the formula and evaluating, you get that time (in seconds) it takes to the object reaches the ground is:

$t=\frac{\sqrt{100-0}}{4}\\\\t=2.5$
